碳钢喷涂防腐涂料在沼气技术中应用广泛。经过KTL电泳防腐涂层做保护的碳钢罐体，经过我们专业人员提供的可靠的装配，从其质量和耐久性来说是不锈钢罐或碳钢衬玻璃钢罐体一个经济实惠的代替品。上部环单元和罐顶结构，直接接触到气体，将使用不锈钢来生产。所有外部加强型材料采用热镀锌材质。

Carbon steel coated with anti-corrosion materials is widly applied in biogas technology. After the carbon steel tanks coated with anti-corrosion materials by KTL electrophoresis, plus reliable assembly craft provided by our professional technician, it could be said that stainless steel tanks or GRF tanks inserted with carbon steel would be one economical substitute product in the point of its quality and durability. The upper ring unit and tank top structure are produced with stainless steel under the consideration that they are directly contact with digested gas. All outside reinforced materials will be hot dip zinc galvanized.
